To all wle-um. it muy concern.:

Be itknown that I, Annuew J. Molinari, n citizen ol' the United St:\tcs,residing'at Framingham, in tht` county of Middlesex, in the State oi' Mussawhuselts, have invented a. certain new andusei'ul 1m|novement in ln- 'sulatoi-Supports, of which the following is a specification, reference being had to the,

accompanyingr draw-'ings The immediate object of this invention is to rovide a 'strong serviceable and particular y convenient form of support for glass and' porcelain insulators of the class com-- monly used for supporting telegraph, telephone, and the like wires', my present 1ini provement heilig specially lvaluable for 'attachment' to treetrunks or limbs and inother situations where it is not feasible, or.

'otherwise desirable, to provide cross-arms -or brackets of'any of the ordinary constructions. A i

My invention is clearlyillustrated in the annexed drawi sin which Figure l is -a side lelevation o aninsulator support einbodying my present improvements and Fig. 2 is a plan view of the same. Fig. 3 isan outer end or face Aview* of thecomplete sup# port and Fig. 4 is a perspective view of .the

`rollwhichserves as a support for the line wire. v

Referring to these drawm the letter a 1 indicates a glass. or porce'ain insulator insulators.

, which be pf ordinary form and constructiorni'fas it 1s my pur ose' to adapt my newly nproved support or use with such The letters b and b denote a strap or clamp-collar whose two parts are "hin ed at b* and'whose terminals` are exand Vspaced apart in parallel relation to' euch other so as to embrace a. bracket Q towhicli they are udjustably clamped by means ot a bolt or screw d. 'lhe bracket 'c 1s adapted to be boltedv or otherwise fastened to a tree or liinb, as will be understood by reference to Figs. l-a'nd 2 of lthe drawings. The clamp collar b-, by means of which the insulator is suspended, lies snugly within the annular groove in which, ordinarily, the line wire is supported.

e" 1n the threaded interior'of the insulator a I' screw au eye-bolt c and in the eye of said bolt I suspend, by means of sister hooks f-g, a. loose pulley or roll L which serves as -lowino' claim hieh tension andfothe'r electrically chargedwires may be readily supported in safe relation to trees and the' like ob'ects.

.aving thus describedfmy invention, I claim as new and wish to secure by Letters Patent In combination with an insulator of the. class' referred to, means for adjus'tablysuportinv said insulator and means for sus- P h 9 pendin f aline wire consisting of an eyebolt remova ly connected-with the insulator, and

an` idle roll depending Vfrom' said eye-bolt and free to sway in everyA direction. :ANDREW J. MORGAN.'
